IMPROVEMENT IN WATER-GAUGES FOR STEAM-BOILERS.

Specification forming part of Letters Patent No. 119,454, dated October 3, 1871.

violent ebullition or boiling of the water, in a steam-boiler is technically termed. At such times it is impossible to tell the exact measurement of the water in the boiler by the gauges now in use.

My invention relates to a device to be applied to the steam and water-pipes used with the ordinary glass watergauge and gauge-cocks, by

which I can determine the actual quantity of water in a boiler notwithstanding the aforesaid condition of priming or foaming.

Figure 1 of the drawing forming part of this specification is a view in elevation of a multitubular boiler, shown one-half in transverse section and half front view, with the proposed arrangement of water-gauge and pipes appertaining to the same shown attached to the boiler. Fig. 2represents a vertical section of the waterchamber on a larger scale, showing the gaugecocks, glass water-gauge, and connecting-pipes attached to the same.

As will be seen by the drawing, Fig. 1, the

water-chamber H communicates with the boiler by two pipes, one attached near the bottom and the other applied to the highest part of the boiler, the top of the steam-drum. I Provided the water in the boiler is quiescent, the water-chamber would always indicate the proper level of the water without any additional attachment by the known law of water seeking its level, but when foaming takes place the water is lifted so as to show a false level hence I have placed a certain arrangement of an inverted conical-pipe in the mouth of the steam connecting-pipe, indicated on the drawing by A, and when deemed neces sary, in other portions of the pipe marked F and E, Fig, 1; also a sluice-valve placed in the pipe at W. By this arrangement I check the rising tendency of the water and at the same time keep open the connection with the dry steam in the steam-drum. This arrangement of introducing my coneshaped device is applicable to all the various water-gauges now in use.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination and arrangement of one or more constricted nozzles A and valve W within the steam passage, forming communication between steam-drum and water-gauge, and directed away from the boiler'with the secondary chamber H, to which the transparent water-gauge is attached, substantially as described.
